Multiple locking means for automobile doors



' Patented Feb. 8, 1938 NITE -STATE'S P'ATENT' OFFICE 4 Haskell Irwin, Oklahoma City, Okl. Application May 19, 1936, Serial No. 80,623

(Ci. 'zo-264 This invention relates to multiple locking means for automobile doors of the character'of in my co-pending application 66,097, filed February 27, 1936, now matured into Pat, No. 2,079,018, dated May`4, 1937, u

The object 'of the invention is to provide a very simple and inexpensive means through the medium of which all of the doors of an automobile maybe simultaneously locked or unlocked under control of a single manually operable member, such as a key, for example.

It is a further object of the invention to provide a device of this character which cannot readily be unlocked from the interior of the car body, so that even if a thief should break a window and get access to the interior of a car;

he could not reach in and unlock the car doors.

Further objects and advantages of the invention will be set forth 'n the detailed de now follows.

In the accompanying drawing:

Figure 1 is a fragmentary perspective view of an automobile body having the device of the present invention applied thereto;

I Fig. 2 is a transverse sectional view of the automobile body illustrating one ofits top bows and v the looking means associated therewith;

Fig. 3 'is a transverse sectional view illustrating the looking means at one side of the car body;

Fig. 4-.is a like view illustrating the 'looking means at the opposite side of the car body, and

Fig. 5 is a detail view of the lock controlled pinion, hereinafter described Like numerals designate corresponding parts throughout the several figures of the drawing. In the particular form of the inventionwhich I have chosen for purposes of illustration, 'a conv'entional form of key controlled cylinder lock 6 carries upon the inner end of its rotative part' 1, a spur gear 8. Partia] rotation of the gear occurs when the key (not shown) is turned in that shown scription which The gear meshes with the teeth 9 of a vertical rack bar III.- The lower end of this rack bar is connected, through the medium of a `connecting rod or cable l-l, witha block !2. 'mie rack bar and block are movable -vertically in a hollow portion i! of the meeting post ll, 'which constitutes a part of the car fram'e and isthe'member against which the free edges of' the front doors !5 and rear doors IS. abut when said doors The block |2 has two curved bolts l'l pivotally' connected thereto in such manner that as the block is drawn upwardly by the movement of the rack bar, said bolts will be projected outwardly, sliding through guide openings I 8 of the post M and entering keepers Is of'the front and re'ar doors at one side of the car-body.

A Bowden or other type of flexible wire 20 is 5 connected to the upper end of the rack bar and its sheath is suitably supported along a top bow 2| of the car body. At the far side of the car, the said wire is attached to a block 12-, which corresponds to the block I! in that it has a pair 10 of curved bolts Il' plvotally connected thereto,

which bolts lie in crossed relation to each other,

as shown; and the free ends of which enter keepers IS" oi' the front and rear doors at said far side'of the car body. 15

However, it will be observed that whereas the curved bolts are at. the u'pper side ofthe block !2 they are at the lower side of the block z so that they will function upon downward movement of said block. By virtue of this arrangement, the looks upon one side of the carbody function upon a downward movement of the rack bar at the 'same time that the bolts upon the opposite side are functioning upon upward movement of said rack bar. V

In other words, when the rack bar moves downwardly and-block 12 is thrust down'wardly,

the bolts I" will be withdrawn from the keepers !9. This same movement will cause the rack bar to draw upon the 'Bowden wire 20 and elevate block z It is clear that this will result in withdrawing bolts I'I' from the keepers.

` Reverse movement of. the rack bar will result in simultaneously looking the doors upon both sides ot the car body. Thus I am able to dispense with all rotative connections between the pinion 8 and the mechanism uponthe far side of the car body and accompllsh all necessary looking movement by a mere end thrust of the transverse connecting member. I 40 It is to be understood that the inventionis not limited to the precise arrangement shown, but that it includes within its purview whatever changes fairly come within either the terms or the spirit of the appended claim.

'Having described my invention, what I claim is:

In a locking mechanis'm for automobilesof the type having a pair of meeting posts and pairsof .doors which abut upon said posts at each side of the car body, a'locking mechanism'comprising a pair of' verticall'y slidable blocks, one at each side of the car body and located in ,said posts, an endwise movable flexible' member engaged with-said blocks, key controlled means for shiftone paircurving downwardly and outwardly be neath their supporting blocks and the bolts of v the other pair curving upwardly and outwardly of their supporting blocks, as and for the purv poses set forth.

HASKELL IRWIN.
